PETROLEUM-TREATING APPARATUS.

Original application filed April 19, 1917, Serial No. 163,171. Divided and this application filed October 2a, 1920. Serial No. c2o,12e. H

treating petroleum, petroleum distillate or petrolum residuum in any suitable way for obtaining petroleum products 1n general,

and particularly for producing light hydrocarbons from heavier oil.

My inventlon resldes in structure for condensing oil vapors, and is of such nature,

as hereinafter more articularly described, as to efiect, preferab y by air cooling, condensation of oil vapors delivered thereto,

and more particularly to effect partial condensation of the oil vapors delivered thereto, leavin some of the oil vapors uncondensed for de ivery to a point beyond the condensin structure.

invention resides in oil vapor condensing structure of the character hereinof Fi Re after described. P

This application is a division from my application Serial Number 287,178, filed April 3, 1919, which latter is in turn a division from my application Serial Number 163,171 filed April 19, .1917, which has matured into Letters Patent No. 1,364,443.

For an illustration of one of the various forms my invention may take, reference may be had to the accompanying drawings, in

which:

Fig. 1 is a side elevational view, partly in section, of the condenser structure and part of an associated still structure.

Fig. 2 is a viein at right angles to the view in Fig. 1 of structure shown therein.

Fig. 3 is a fragmentary view of'part of the structure ofFig. 1 as seen from a direc-' tion at right angles thereto. Figs. 4 and 5 are sectional views, partly in plan, taken onthe lines M and 55 eelky high in the air, is carried the condenser I to the drawing, S represents a s eifical ti upon whose upper end, preferstructure; The still may be provided with a manhole 1.

Within the still S exist or are produced oil vapors, generally those of oils of difierent boiling or condensation points. These vapors are led off from the still S through the vapor outlet pipe 20 communicating through valve 21 with a sweat-out line or pipe 22, and with the pipe 23 leading to the safety valve 24 whose discharge side communicates with a vertically extending pipe 25. The main vapor line or pipe 20 communicates also through the valve 26 with the upwardly and then downwardly extending vapor line or pipe 27, which communicates with the initial header 28 of the aerial or air condenser. The header 28 communicates with a plurality of transversely extending initial manifolds 29 with which communicate the numerous smaller vertically extending ipes 30 connected in various groups throug the top connecting pipes 31 with the numerous small downwardly extending pipes 32 communicating with the transverse terminal manifolds 33, which latter all communicate with the terminal header 34:. The pipes 30 and 32 are preferably arranged, as indicated, in various groups, the ascending and descending pipes of a group being disposed at difi'erent distances longitudinally of the manifolds 29 and 33, the pipes 31 connecting the diflerent pipes of a group and extending diagonally from the upper ends of the pipes 30 to the upper ends of the pipes 32 of the same group. The numerous pipes 30 and 32, and associated connections, are housed within the structure. 35 open at its bottom and having at its top an open work cover 36 of wire mesh or the'like, whereby air. circulates initial or intake header.

pipes for ab- From the-transverse manifolds 29 and 33 extend downwardly the several pipes 37 which communicate at their lower ends with a pipe 38, with which is connected the riser ipe 39 communicating through valve 40 with the still S at its top, this pipe structure constituting a runback, whereby there are returned into the still S those heavier oils whose vapors have been condensed in the air condenser and'which have been only partially, if at all, subjected to the desired treatment.

There is connected with the header 34 of the air condenser a pipe 41, to which is connected the telltale pipe 42 controlled by valve 43. The pipe 41 communicates through the valve 44 and the pipe 45 with the intake of the pressure reducing valve 46, whose outlet communicates through the pipe 47 and valve 48 with the vapor line or pipe 49, which conducts away from the aircooled condenser structure the uncondensed vapors, those of lower boiling point oils. The pipes 41 and 49 are also connected through the normally closed by-pass valve 50. e

The vapors of the heavier oils entering the condenser structure are condensed and returned to the still S through the runback connections 37, while the lighter vapors of the desired products are not condensed in the air condenser, but pass off through the reducing valve 46, the still S and condenser structure generally being under pressure, as for example, in the production ofgasolene or light oils by cracking heavier oils. Uncondensed' lighter vapors emerging from the reducing valve 46 are conducted off to a water cooled condenser, not shown, or to any other suitable device or desired destination. I
